如何将 SWF 文件批量打印为 PDF？

Question 1

我也一直在寻找同样的东西。好吧，我也找不到任何特定的库来完成这项工作。但至少我们能够使用 GUI 自动化工具来自动化这个过程。

有很多库和独立应用程序可以完成这项工作。我认为比较有希望的一个是奥图伊特。

但作为一名 Python 粉丝，我发现了一个很棒的库，叫做pywinauto并编写了以下脚本来转换我的 swf 文件：

"""Convert all swf files in this directory to a pdf file using Firefox.

Note that some parameters in this script need to be adjusted according to
user's printer setup, screen resolution, etc.

 * https://github.com/vsajip/pywinauto/blob/master/examples/SaveFromFirefox.py

这种方法有其自身的局限性。例如，在转换过程中您将无法使用计算机，因为鼠标和键盘由脚本控制。脚本需要针对各个计算机进行调整。此外，GUI 控制过程应该比设计用于执行相同工作的 CLI 应用程序慢得多。但是，这仍然比手动转换更容易、更快。

PS 我忍不住要提一下西库利. 另一个用于 GUI 自动化的出色的 Python 库。

上述方法生成的是矢量图形，但如果有人对栅格化的 .png 文件感兴趣（可以使用免费工具轻松转换为 pdf），他们可能想swfrender尝试工具包。目前，最新的适用于 Windows 的稳定二进制版本是 0.9.0 (2009-07-21)。但我建议尝试开发快照，它提供了更多选项，包括用于调整输出文件分辨率的swftools-2013-04-09-1007.exe选项。-r

Question 2

以下是我使用 pywinauto 做出的贡献。

我使用 Internet Explorer 作为浏览器（因此将 Internet Explorer 设置为 swf 文件的默认程序），因为我发现它加载 swf 文件的速度最快（我知道……很奇怪吧）。

我还使用 Adobe Acrobat 进行打印。（不过，大多数程序的打印对话框句柄似乎都类似，因此您可能不会遇到麻烦）。因为我使用了 Adobe，所以我必须将打印对话框的句柄从

window.OK.click 到 window.Print.click (第 61 行)

您可能还需要更改下面一行（第 43 行）的值。因为您的屏幕分辨率可能与我的不同。

browser_tab.click_input（坐标=（1440，2060））

如果解释得不好，请原谅，另外因为它是 python，请检查下面代码中的缩进是否正确。

我使用 SWAPY 来帮助获取每个窗口的控件标识符。但是 SWAPY 使用的是旧代码（尽管仍然非常有用），所以我更新了代码以反映和支持 pywinauto 的当前版本（至少对我来说是这样）。如果你查看它，函数调用大致相同，只是从 camelcase 转换为 underscore_case。
